With a Z-score of -0.17 (43.1th percentile), this represents normal volume ; hippocampal volume measures 7,146 mm³, 2.6% above the reference mean. With a Z-score of 0.22 (58.7th percentile), this represents normal volume ; whole brain volume measures 1,044,640 mm³, 1.5% above the reference mean. With a Z-score of 0.20 (57.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,620 mm³, 8.8% below the reference mean. With a Z-score of -0.58 (28.2th percentile), this represents normal volume ; fusiform gyrus volume measures 18,417 mm³, 1.9% above the reference mean. With a Z-score of 0.17 (56.7th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,008 mm³, 0.8% below the reference mean.

  "gpt_diagnosis": "**Reasoning:** All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 26, MoCA 25) are also within normal limits for age, and the absence of APOE4 further reduces Alzheimer's risk.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
